Paul Vixie’s cron daemon, a fully featured crond implementation.
Vixie cron contains a race condition relating to atime and mtime values of temporary files.
A local attacker could change the modification time of files, possibly resulting in a Denial of Service condition via a symlink attack.
There is no known workaround at this time.
All Vixie cron users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-process/vixie-cron-4.1-r14"
OS | Version | Architecture | Package | Version | Filename |
